Disclosed is an improved hearing instrument of the type generally having a microphone having an input for receiving ambient audio signals and an output for generating an electrical signal corresponding to the audio signals, a signal processor having an audio channel input connected to the output of the microphone for receiving and processing the electrical signal to produce a processed electrical signal and an output for outputting the processed electrical signal, where the signal processor is programmable through a communication port, and a speaker having an input connected to the output of the signal processor and an output for generating an audio signal corresponding to the processed electrical signal. The improvement consists of an interface for wireless programming of the signal processor. The interface has a watchdog circuit and a switch operatively connected between the output of the microphone and the input of the signal processor, another switch operatively connected between the output of the signal processor and the input of the speaker and a programming interface operatively connected to the switch, to the other switch and to the communication port of the signal processor, for translating the program codes into a programming language compatible with the programming language of the signal processor in order to program the signal processor by communicating with the signal processor through the communication port. This improved hearing instrument includes both "analog" and "digital" hearing instruments, and can be programmed at a remote location from the offices of a hearing aid specialist, through any type of channel.
